Can't save changes in game setting

Hi all! I am the master of a game and I bought the Player's Handbook D&D 5e and the  Guildmasters' Guide to Ravnica. Now I want to share them with other 5 players but when I go to the game settings, checking the "Yes" to share them, and I click on "save changes" nothing happens.

Hello Lorenzo S., This issue deals with the limitations on Compendium Sharing based on account type. As a free user, you  may only share their purchased compendiums with one active game that contains no more than themselves plus 5 players (6 total). Check your games and only turn on Compendium Sharing for the game you would like to use it on. We hope this information helps. Let us know if you have any additional questions. Happy rolling.
